Actionmailer issues...any experts?

Rails
1

I have a rails app that can send emails to gmail, yahoo accounts. But
when it comes to more obscure accounts like [email protected] or
[email protected], the mail never arrives even though the log shows
that
the email was sent. Any ideas why this may be happening?

I have sent an email directly through the same web server through the
command line using

mail -s and that worked. Why doesn’t it work through my rails app?

here are my configuration settings (mostly default)

Disable delivery errors, bad email addresses will be ignored

config.action_mailer.delivery_method = :smtp
config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_deliveries = true
config.action_mailer.default_charset = “utf-8”

config.action_mailer.smtp_settings = {
:address => “localhost”,
:port => 25,
:domain => “my-app.com”
}

help please!

thanks
Tony

What does SPF mean? No when I use mail -s, the email is sent from
[email protected]

Different hosts might be more or less restrictive when it comes to
spam (eg blacklists of ip ranges, whether they check SPF records etc…)

I know nothing about mail -s. Does it send email through the same smtp
server as your rails app. Would it set the same return-path/from
address (which is what matters for SPF) as your rails app ?

When you send an email from [email protected] the mail server on the other
end can lookup the SPF record for the domain bar.com (this info is
part of the DNS records for bar.com). In a nutshell the SPF records
are used to determine whether the server sending mail from
[email protected] is allowed to send mail on behalf of that domain.
Different mail servers receiving mail may be more or less stringent:
it could merely count towards a score that determines whether the
message is classed as spam or might lead to it being rejected
altogether.
